A switching circuit includes a first half-bridge circuit, a second half-bridge circuit and a voltage divider circuit connected in parallel with each other and a DC input power (V). The first half-bridge circuit includes a first pair of series connected switches and the second half-bridge circuit includes a second pair of series connected switches.

Four-switch three phase DC-DC resonant converter

The disclosure relates to a controller for a power converter, the power converter comprising a first switch and a second switch, wherein the controller is configured to receive a first control signal based on a first drain-to-source voltage of the first switch; receive a second control signal based on a second drain-to-source voltage of the second switch; derive a first switch control signal based on the first control signal and control the first switch by providing the first switch control signal to the first switch; derive a second switch control signal based on the second control signal and control the second switch by providing the second switch control signal to the second switch; wherein the first switch control signal and the second switch control signal each comprises turn-on edges and turn-off edges. Furthermore, disclosure also relates to corresponding methods, a non-transitory computer readable medium.

Power converter, a controller and a system

The present invention relates to a bi-directional DC-DC converter comprising: a first terminal, a second terminal, a transformer circuit, a first high voltage side coupled to said first terminal, and a second low voltage side coupled to said second terminal; wherein said first high voltage side and said second low voltage side are coupled to each other by means of said transformer circuit, and said first high voltage side comprises a resonant tank circuit coupled between a first bridge circuit of said first high voltage side and a high voltage side of said transformer circuit. Furthermore, the invention also relates to a system comprising at least two such bi-directional DC-DC converters.
